模型'feedback‘没有关联到模型'user’- Sequelize (Node JS)

const { Sequelize, Model, DataTypes } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql',
});

class User extends Model {}
User.init({
  // 用户模型的属性定义
}, { sequelize, modelName: 'user' });

class Feedback extends Model {}
Feedback.init({
  // feedback模型的属性定义
}, { sequelize, modelName: 'feedback' });

// 定义关联关系
Feedback.belongsTo(User); // 或者 Feedback.hasOne(User);

// 导出模型
module.exports = { User, Feedback };
